Greetings I initially installed the TV Server (MS SQL DB) . I followed the instructions in the sticky post about how to configure a Hybrid Tuner. After run an ATSC (Standard QAM) channel scan, all the channels came up as UNKNOWN (See Screenshot 1).

In another post here, I read another post that said not to do the Hybrid configuration if that happens. So I completely uninstalled the TV Server application and the MS SQL DB.

After the re-install, I went straight to the channel scan. A few channels came back NOT UNKNOWN (See Screenshot 2), but most of them came back as UNKNOWN.

Attached as well is export.xml and TV Server directory.

Questions:

1) What is the difference between the red and green icons in Screenshot 2? Does that just specify which channels info could be found for?

2) Why are all those stations discover as UNKNOWN?
